Introduction

If it is needed to retrieve data about the machine configuration settings that are applied to the entire computer resided applications, do as follow:

1. Add new project
2. Add a button to the Form1
3. Add the following code in the editor

Code

private void GetMachineConfigurationSections()
{
    try
    {
        /* Create a new cofiguration instance and specify it to target the,the machine configuration settings as follow */
        Configuration oConfiguration = ConfigurationManager.OpenMachineConfiguration();
        // This variable help us to know the section number
        int SectionsNumber = 0;
        MessageBox.Show("The machine configuration sections");
        /* Get all sections in the machine configuration file. It can be found,in the directory : C:\Microsoft.NET\Framework\version\config */
        foreach (ConfigurationSection section in oConfiguration.Sections)
        {
            MessageBox.Show(string.Format("The section name is : {0}",section.SectionInformation.Name));
            //Increment the sections' number to get the count 
            SectionsNumber++;
        }
       
        //Display the sections count 
        MessageBox.Show("The number of sections");
        MessageBox.Show(SectionsNumber.ToString());

        //Display the machine configuration file path
        MessageBox.Show("The machine configuration section path");
        MessageBox.Show(oConfiguration.FilePath);
    }
    catch(ConfigurationErrorsException caught){ MessageBox.Show(caught.Message);
}

private void button1_Click(object sender, EventArgs e)
{
    GetMachineConfigurationSections();
}

It is possible to get other information instead of the section name by using other attributes of  section.SectionInformation  object
